most people feel a fresh water rinse, air dry and flake will extend the life of the spin. I usually do this but its a pain.. plus i live in an apartments so that means... in the bath tub... then hanging in my apt for 2 days. i have left my spin rigged also when i get lazy.

If you are flying a used spin and dont care to much about it i say leave it. if its new... and you love the crispyness... treat it well.

a trick i learned from an olympic cat sailer to spread out the patches for dousing is to use a nylon line ball after the first patch, and use a long (8-12") bowline knot at the top patch. this will help get the first patch in the sock without the second one right with it.

The ring post was: run the retrieval line through a plastic ring and tie a bungee cord from the ring to the clew. this will pull the sheets in with the spin. it is great for getting lines off your tramp and helps hide some extra retrieval line from your tramp. i ended up needing about 3' of bungee or i would have had to replace/increase my sheets. I figure .63 cents of extra bungee was better than new sheets for $40.

I live in Arizona and the "WET KITTY" is kept under an RV shade. There isn't much chance of it getting wet. I also have it wrapped in a doubled up tarp. One of the brown and silver ones from HD.
I think that if those are the only considerations, it should be ok.
It's much easier to set up and and tear down at the lake.

offtopic..but related. I am fixing up an old 5.2. You picture shows the setup for tensioning the daggerboards so they don't slide. Do you have a closer shot? all lines and bungie cords on my boat are rotted, and I don't know how to set up the daggerboard. My 5.2 is like yours..it has the aluminum pole down the center of the tramp.
Thanks,
Dave
